Vitamin D Deficiency Attenuates High-Fat Diet-Induced Hyperinsulinemia and Hepatic Lipid Accumulation in Male Mice

Abstract: It is increasingly recognized that vitamin D deficiency is associated with increased risks of metabolic disorders among overweight children. A recent study showed that vitamin D deficiency exacerbated inflammation in nonalcoholic fatty liver disease through activating toll-like receptor 4 in a high-fat diet (HFD) rat model. The present study aimed to further investigate the effects of vitamin D deficiency on HFD-induced insulin resistance and hepatic lipid accumulation. Male ICR mice (35 d old) were randomly a… Show more

“…Overall, our findings that vitamin D insufficiency had no effect on BMI in our mice run contrary to findings by Bastie et al [14] and to a lesser extent Liu et al [13], where diet induced vitamin D deficient mice were resistant to “western” and high fat diet induced weight gain, respectfully. However these studies induced vitamin D deficiency concurrently with alterations in diet.…”

“…Contrary to what is seen in human trials, animal studies appear to show that vitamin D may promote weight gain. Vitamin D receptor (VDR) knock-out mice were shown to be resistant to weight gain [11, 12], as were diet-induced vitamin D deficient/insufficient mice to high fat [13] and “western” diets [14]. Additionally, over-expression of VDR in adipocytes induced weight gain in mice [15].…”

“…These VDR null mice fed a high-fat diet displayed reduced lipid accumulation in the liver through greater fatty acid oxidation and increased expression of uncoupling proteins (UCPs), UCP-1, UCP-2, which increases energy expenditure [46]. Dietary induced vitamin D deficiency also alleviates hepatic lipid accumulation, upregulates key enzymes involved in fatty acid oxidation and uncoupling protein 3 (UCP-3) [47]. UCP-1 is an important regulator of proton flux, and can allow dissipation of the proton gradient across the mitochondrial inner membrane in specialised tissues such as brown adipose tissue [46].…”

“…Moreover, several studies have also report that low serum 1,25(OH) 2 D 3 levels are associated with a higher body mass index (BMI) and body fat mass in healthy adults (Kayaniyil et al, ; Parikh et al, ). However, our previous study also shows that vitamin D deficiency alleviates high‐fat diet‐induced overweight, hyperinsulinemia, and hepatic lipid accumulation in male mice (Liu et al, ). Thus, it is especially interesting to further explore the effects of vitamin D deficiency on acute alcohol‐induced hepatic lipid accumulation in mice.…”
